DRY CLOSET.

SPECIFICATION forming part of Letters Patent No. 591,582, dated October12, 1897.

Application filed A t 27,1896. Serial No. 604,072. (No model.)

To all whom it flea/y concern I Be itknown that-I, EDGAR W. ANTHONY, ofBoston, in the county of Suffolk and State of Massachusetts, haveinvented certain new and usefullmprovements in Dry Closets, of which thefollowing is a specification.

This invention relates to dry closets for school or other buildings inlocalities where there are'no sewer systems and where'the waste cannotbe carried away by running water.

The objects of the invention are to provide a closet of the charactermentioned which shall be so constructed and arranged as to be free fromodors or gases and to be sanitary to the highest degree, to provide awaste-receptacle in which the liquids shall be separated from thesolids, whereby the latter may be desiccated and finally cremated, and'to construct the closet in such way that the waste-receptacle shall bearranged in the path of the heated air or the products of combustionfrom a fire to dry the waste and be arranged: in such way that thecurrents of air shall be drawn through the seats and discharged throughan aspirating-shaft,- whereby the room in which the closet'is located isthoroughly ventilated.

To these ends the invention consists of a closet possessing thosefeatures of construction and arrangement which I have illus trated inthe drawings, and hereinafter described in detail and claimed.

Reference is to be had to the accompanying drawings,and to theletters-marked thereon, forming a part of this specification, thesameletters designating the same parts or features, as the case may be,wherever they occur.

Of the drawings, Figure 1 is a perspective view of a closet embodying myinvention. Fig. 2 is a vertical longitudinal section through the sameand illustrates the currents ofair passing through the same. Fig. 3 is avertical cross-section illustrating the wastereceptacle in its normalposition. Fig. 4 is a similar section showing the receptacle inverted todischarge the waste for the purpose of cremating it. Fig. 5 shows thehand-wheel and gearing foroscillating thewaste-receptaele toinvert it.

Referring to the drawings, a designates the I wall ofa room, which 'isutilized as the rear wall of the closet. I) is a low wall built at ashort distance in front of the wall a, so as to leave a chamber betweenthem which is floored with fire-brick c c. WVithin theehalnber thusformed is placed a waste-receptacle (indicated as a whole by d) andabove it are placed the seats'e e.

The seat-support f consists, preferably, of iron castings of the shapeshown and each having the lower edge of the forward vertical partresting upon a sill 9, extending along the top of the wall I) and havingits rear edge extending into the wall 0Q, to be supported thereby, as isclearly illustrated in Figs. 3 and 4.

For the purposes of illustrating my invention I have shown but two seatsseparated by a partition h; but itwill be understood that there may beas many seats as desired, the waste-receptacle being of a length toextend under all or a portion of them.

The seats are provided with covers 1', hinged in the rear and havingcushiOning-buifers, so as to leave a space between the said seats andthe covers for the passage of the air when the covers are closed, aswill be hereinafter explained.

The waste-receptacle d is provided at its ends with trunnions klc,journaled in the crossbraces Z, extending from the walla to the wallI), there being flanges m abutting against the cross-braces to preventany longitudinal movement of the said receptacle. The saidwaste-receptacle is semicylindrical in shape,

with its convexv sides downward, and has closed ends it it. One end ofthe chamber between the front and rear walls is closed by an arched wall42, having apertures through which'the trunnions extend, and also forthe passage of the heated air and products of combustion from the firein afurnace located at that end of the closet. Said furnace (des ignatedas a whole by 0) is provided with a grate p for the fuel and with doorsq and 1", each provided with dampers. 4 v I The top of the furnaceis'closed byaplate s, so that the products of. combustion and heated airpass from said furnace through the said chamber beneath the seats andare discharged through an aspirating shaft or chimney t at the other endof the closet, which communicates with the said chamber between thefront and rear walls.

The waste-receptacle is of such width that its edges o in press againstor rest on a sill g of the wall I), and a plate 03 inserted in the walla, so that the compartment above the receptacle is closed to theentrance of the products of combustion from the furnace 0, although itcommunicates with the aspiratingshaft, as shown in Fig. '2.

\Vhen the receptacle is in the position illustrated in Fig. 3, the wastematter may be discharged therein, and upon inverting it, as illustratedin Fig. 4, the matter therein is dumped or emptied upon the floor c.

The concave face of the receptacle is provided with a concave-convexbridge y, hinged at .2 to cars projecting inward therefrom, said bridgebeing provided with an aperture ct for the admission of liquids to theduct thus formed between it and the receptacle.

There may be a bridge beneath each seat for the reception of solidmatter, or else a single bridge may extend the entire length of thereceptacle, there being asuitable nu mber of apertures leadingthereinto.

The bottom of the receptacle slopes to one end, where there is adischarge-aperture b directly over a pipe 0, leading to a blinddrain orcesspool, as desired.

The solid matteris retained upon the bridge 7 while the liquids aredischarged through the aperture b into the tube or pipe 0, and since thereceptacle is in the path of the products of combustion and heated airfrom the furnace the waste solid matter is thoroughly desiccated anddried and afterward cremated, in a way to be described. The trunnions kare suitably protected by bridges or caps d d at each end of the closet.

The aspiratingshaft may be formed of brick or any other suitablematerial and extends up high enough to discharge the smoke, gases, andodors into the air at a proper distance from the ground. The end of thecloset opposite the wall a is closed by the wall e and a door f.

For inverting the waste receptacle the square end g of one of thetrunnions 7a is provided with a pinion h, which may be rotated by apinion "6 upon a shaft j, through the medium of reducing-gears Z and m.

The shaft j is provided with a hand-wheel m, there being a dog 0 adaptedto enter the teeth of the pinion t and prevent it from rotating when thereceptacle is in an inverted position, as shown in Fig. 4:.

p is a rod arranged horizontally and above the seats in such way as toengage the lids or covers when the latter are raised and prevent themfrom swinging back, whereby the covers will fall by gravity when theseats are not occupied.

\Vhen the solid waste matter has accumulated within the receptacle tothat extent at which it is desired to cremate it, it having beenseparated from the liquid waste matter and having been thoroughlydesiccated and dried and covered with sawdust and petroleum, thereceptacle is inverted by means of the wheel at and the solid matter isdischarged upon the floor 0. Then when it is set on fire it is crematedand reduced to ashes without emitting any disagreeable odors or gases,as would be the case were it attempted to burn such solid matter withoutfirst drying it.

The bridges 1 being hinged, hang in the position shown in Fig. 4, so asto discharge therefrom any matter that may have accumulated thereon.

By constructing a closet in accordance with the foregoing description itwill be seen that the space or flue in which the waste-receptaole isplaced is practically closed against the admission of air except throughthe furnace 0 and the apertures in the seats, and that likewise when thewaste-receptacle is in its normal position the passage of the productsof combustion through the apertures in the seats is absolutelyprevented. The products of combustion and the heated air passing fromthe furnace pass under this waste-receptacle and are discharged into theair through the aspirating-shaft, in which a steady draft is maintained,so that the air in the room is drawn down through the apertures in theseats and through the space between the covers and the seats into theshaft, thereby preventing any eurrents coming out through the aperturesin the seats and discharging gas in the room. Hence a perfectventilation in the room is secured by reason of the draft through theapertures in the seats, which is maintained by the draft in theaspirating-shaft.

The waste-receptacle being situated in a flue placed between the furnaceand its chimney, or, as I term it, the aspirating-shaft, insures thatthe solid matter shall be thoroughly dried before an attempt is made toburn or cremate it, and therefore when the cremation takes place, asbefore described, no noisome odors or gases are expelled, as would bethe case were it attempted to cremate the mass while in a moistcondition. The peculiar construction of the waste-1e ceptaele enables athorough separation of the liquid waste from the solid material, wherebythis desiccation of the solid matter is effected.

It will be observed that by placing the aspirating-shaft at one end ofthe chamber or flue and the furnace at the other end of the flue I amenabled to obtain a direct draft beneath the waste-receptacle, so thatthe matter is dried rapidly and thoroughly. The receptacle extendsbeneath the entire battery of seats, and its trunnions project outbeyond the latter and are covered and protected by bridges or. caps, sothat they are unexposed. By forming one single receptacle the wastematter is discharged thereinto without being deposited upon anystationary portions of the closet, as it would be were there a singlereceptacle for each seat.

It will be further observed that the metal- .lic seat-support has aforwardly-projecting flange resting upon a sill g, which latter has asloping upper surface projecting over the edge of the receptacle, sothat any liquid matter striking against the seat-support will find itsway into the receptacle, and, moreover, the entire mass of Waste may bedumped upon the floor of the flue at one single operation, there beingonly one single trunnion, which is arranged at the end of the row ofseats out of the way of the occupants of the seats. The

receptacle being heavy I find it necessary to employ the hand-wheel andthe multiplyinggearing for reversing it, and hence the gearing ispreferably located adjacent to the furnace, when both can be attended tofrom the same end of the row of seats.

When the desiccated matter is being burned, the receptacle is inverted,so as to form with the bottom and side walls of the chamber a largeuninterrupted flue, so that a'good draft is obtained and the matter maybe quickly consumed. This would not be possible were the receptacle soformed as to have projecting portions, thereby causing eddies andpreventing the fire from burning well.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, though Without attempting to set forthall of the forms in which it may be made or all of the modes of its use,I declare that what I claim is 1. In a closet, in combination, afurnace, an aspirating shaft or chimneyconnected with said furnace by aflue, a series of seats located above the flue, a single invertibleconcavoconvex waste-receptacle located in saidflue below the seats andextending entirely across said flue, and also having closed ends,wherebythe products of combustion pass below the receptacle to theaspirating-shaft, and are prevented from-gaining access to space abovethe receptacle and below the seats, and means for inverting the saidreceptacle to discharge the waste matter, said receptacle when invertedforming the upper wall of an uninterrupted flue. I

2. In acloset, in combination, afurnace, an aspirating shaft or chimneyconnected with said furnace by a flue, a series of seats located abovethe flue, sills on both sides of the said flue, and an invertibleconcave-convex wastereceptacle pivoted in the flue and located below theseats, to form the upper wall of the flue, said receptacle havinglongitudinal lips or flanges to rest against said sills, when saidreceptacle is in its normal position and when it is inverted.

3. In a closet, the combination with a line of seats, a furnace atoneend of said line of seats, and an aspirating shaft or chimney at theother end of said line of seats, of a single waste-receptacle extendingcontinuously under the line of seats and situated so as to be under-theinfluence of the heated air and products of combustion from the furnace,

said receptacle being provided with movable means, locatedin the bottomthereof, for separating the liquid matter from the solid matter, anddischarging said liquid matter while the solid matter is retained.

4. In a closet, the combination with a line of seats, a furnace and anaspirating shaft or chimney, of a single invertible waste-receptacleextending under the line of seats and situated so as to be under theinfluence of the heated air and products of combustion from the furnace,said receptacle being provided with a discharge-aperture for the liquidwaste, and a series of movable means for receiving and maintaining thesolid waste matter, one of said means being-located under each seat.

5. In a closet, the combination with the seat-supports, and the seats,of a waste-receptacle arranged beneath the said seat-s, said receptaclebeing constructed to discharge the liquid waste, and being provided withhinged bridges to receive the solid waste, and means for inverting thesaid receptacle.

6, In a dry closet, the combination of afurnace, an aspirating-shaft, ahorizontal flue connecting the same, ledges or flanges along oppositelongitudinal walls of said flue and projecting thereinto to present bothupper and lower abutments, a waste-receptacle extending longitudinallyof the said flue and pivotally supported at its ends to render itinvertible, said receptacle underlapping one of theflue-ledges along onelongitudinal edge and overlapping the other of said flue-ledges alongthe opposite longitudinal edge whereby in both positions of saidreceptacle the flue is closed by abutment of the receptacle against theledges; and seats over the receptacle which is common to them all.

7. In a dry closet, the combination of a furnace, an aspirating-shaft, ahorizontal flue connecting the same, a waste-receptacleextendinglongitudinally of the said flue and invertible therein, said receptaclecarrying arches or bridges on one side and pivotally connected therewithso as to depend automatically when the receptacle is inverted; and seatsarranged above the receptacle and over the said bridges respectively.

Intestimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 24th day of August, A. D.1896.
